Greetings,

Apologies for the late reply, as things have been a bit hectic at work lately.

Thank you very much for the guidance and the suggestion to move the logic into
gpiolib. This is a far better approach than my initial one. As this is my first
time submitting code to the Linux community, I am very grateful for your
mentorship and support.

This series (v2) addresses a limitation in the I2C bus recovery 
mechanism where certain open-drain GPIOs are incorrectly identified 
as input-only, preventing the recovery logic from functioning.

Following the suggestion from Linus Walleij, this version drops the 
previously proposed "force-set-sda" DT property. Instead, it 
introduces a generic helper in the GPIO subsystem to identify 
single-ended configurations. This allows the I2C core to reliably 
enable recovery for open-drain lines regardless of the 
instantaneous hardware direction reporting.

Changes in v2:
- Replaced DT-based "force-set-sda" with a gpiolib helper.
- Added gpiod_is_single_ended() to drivers/gpio/gpiolib.c.
- Updated i2c-core-base.c to use the new helper.

  gpiolib: add gpiod_is_single_ended() helper
  i2c: core: support recovery for single-ended GPIOs
